AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
302 AM PST FRI JAN 8 2016

.SYNOPSIS...MULTIPLE STORM SYSTEMS ARE EXPECTED TO MOVE THROUGH
NORTHWEST CALIFORNIA OVER THE NEXT WEEK. RAIN AND HIGH ELEVATION
SNOWS WILL OCCUR WITH EACH SYSTEM. THE NEXT STORM SYSTEM IS
EXPECTED TO ARRIVE THIS EVENING.

&&

.DISCUSSION...A HIGH AMPLITUDE LONG WAVE RIDGE IS CURRENTLY SITUATED
OVER THE WEST COAST. HOWEVER...AN EL NINO LIKE SUB-TROPICAL JET
HAS DEVELOPED WHICH IS STRONG ENOUGH TO PULL SYSTEMS
UNDERNEATH/THROUGH THE RIDGE TOWARD CALIFORNIA. MODEL GUIDANCE IS
UNANIMOUS THAT AN ACTIVE STORM PATTERN WILL CONTINUE WITH MULTIPLE
WEAKENING FRONTS AND LOW PRESSURE SYSTEMS APPROACHING THE
COAST...FIGHTING AGAINST THE RIDGE. NO SIGNIFICANT STORMS ARE IN
THE OFFING BUT RAIN...MOUNTAIN SNOW...AND SOME GUSTY SOUTH WINDS
ARE EXPECTED APPROXIMATELY EVERY OTHER DAY OR TWO THROUGH THE END
OF NEXT WEEK.

THE NEXT IN THE SERIES OF STORMS WILL BEGIN TO IMPACT THE REGION
THIS EVENING AND CONTINUE THROUGH TONIGHT. SOUTHERLY WINDS IN
ADVANCE OF THE FRONT WILL LIKELY BRING SOME GUSTS BETWEEN 30 AND
40 MPH TO MOUNTAIN RIDGE TOPS AND SOME COASTAL HEADLANDS.
CONSIDERING MODELS HAVE TRENDED TOWARD A WEAKER FRONT THAN
24-HOURS AGO...GUSTS TO 45 MPH ARE EXPECTED TO BE FEW AND FAR
BETWEEN AND A WIND ADVISORY HAS NOT BEEN ISSUED AT THIS TIME.
HOWEVER THE SOUTHERLY WINDS WILL RESULT IN RAIN SHADOWING FOR THE
HUMBOLDT BAY AREA AS PRECIPITATION ARRIVES. PRECIPITATION WILL
RANGE FROM 0.25-1.00 LIQUID EQUIVALENT INCHES ACROSS THE REGION
WITH THE LEAST RAINFALL ON THE NORTH SIDE OF MOUNTAIN RANGES. SNOW
LEVELS WILL GENERALLY RANGE FROM 4000-5000 FEET EXCEPT IN TRINITY
COUNTY WHERE LEVELS MAY FALL TO AS LOW AS 3500 FEET LATE IN THE
NIGHT. THERE MAY BE SOME IMPACTS AT ELEVATIONS OVER 4000 FEET IN
TRINITY COUNTY...INCLUDING THE HIGHER ELEVATION PORTIONS OF
HIGHWAY 36...BUT CONFIDENCE IS NOT HIGH ENOUGH THAT SNOW WILL BE
GREAT ENOUGH TO REQUIRE SNOW CHAINS TO ISSUE A WINTER WEATHER
ADVISORY AT THIS TIME. THE DAY SHIFT WILL EXAMINE TEMPERATURE
TRENDS AND DETERMINE IF AN ADVISORY IS NEEDED LATER TODAY.

PRECIPITATION WILL DECREASE TO SHOWERS SATURDAY MORNING AND SOME
SUNSHINE WILL BE POSSIBLE AT THE COAST IN THE AFTERNOON. CLEARING
SKIES OVERNIGHT WILL LIKELY ALLOW INTERIOR VALLEY FOG TO DEVELOP
AS TEMPERATURES COOL. SOME FREEZING FOG IS POSSIBLE WHICH WOULD
RESULT IN SOME ICY ROADS.

ADDITIONAL STORM SYSTEMS WITH SIMILAR CHARACTERISTICS WILL MOVE
THROUGH NORTHWEST CALIFORNIA SUNDAY NIGHT INTO MONDAY...AROUND MID-
NEXT WEEK...AND THEN AGAIN LATE NEXT WEEK. NO SINGLE STORM SYSTEM
STANDS OUT AS SIGNIFICANTLY STRONGER THAN THE OTHER AT THIS TIME.
THUS THE MAIN CONCERNS THIS WEEK WILL CONTINUE TO BE MINOR SNOWS
WHICH COULD RESULT IN CHAIN REQUIREMENTS ON THE HIGHEST MOUNTAIN
PASSES AND POSSIBLE ADVISORY LEVEL WIND GUSTS IN ADVANCE OF EACH
FRONT. RPA

&&

.AVIATION...MVFR CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS
WILL CONTINUE AT KCEC AND KACV THROUGH THIS MORNING DUE TO REDUCED
CEILINGS AND/OR VISIBILITIES AS SHOWERS MOVE THROUGH THE AREA AT
TIMES THIS MORNING AND DUE TO PATCHY FOG AT TIMES. VFR CONDITIONS
AND LIGHT TO MODERATE WINDS WILL PREVAIL AT KCEC AND KACV THIS
AFTERNOON AND EVENING. WINDS WILL BECOME MODERATE AND GUSTY LATE
THIS AFTERNOON AND OVERNIGHT AND SHOWERS WILL MOVE THROUGH THE AREA
AS A WEAK COLD FRONT MOVES THROUGH THE REGION. THE SHOWERS WILL
RESULT IN LOWER CEILINGS AND MVFR CONDITIONS WILL OCCUR AT KCEC AND
KACV THIS EVENING AND OVERNIGHT TONIGHT. MVFR TO IFR CONDITIONS
WILL CONTINUE AT KUKI THROUGH THIS MORNING DUE TO PATCHY FOG
REDUCING CEILINGS AND VISIBILITIES. VFR CONDITIONS WILL PREVAIL AT
KUKI THIS AFTERNOON. MVFR TO IFR CONDITIONS AND LIGHT TO MODERATE
WINDS WILL OCCUR AT KUKI OVERNIGHT WITH SHOWERS REDUCING CEILINGS
AND VISIBILITIES.

&&

.MARINE...A SERIES OF OFFSHORE LOW PRESSURE SYSTEMS AND FRONTAL
BOUNDARIES WILL CONTINUE PRODUCING ELEVATED WINDS AND/OR SEAS AT
TIMES ACROSS THE WATERS THROUGH NEXT WEEK. A WESTERLY SWELL WILL
PROPAGATE ACROSS THE WATERS THROUGH SATURDAY. SMALL CRAFT ADVISORIES
ARE IN EFFECT ACROSS THE NEAR SHORE WATERS THROUGH EARLY SUNDAY
MORNING DUE TO ELEVATED WINDS AND/OR SEAS. A SMALL CRAFT ADVISORY
REMAINS IN EFFECT ACROSS THE OUTER WATERS THROUGH 9 AM THIS MORNING.
